Cl. 238-349 8 Claims ABSTRACT OF THEDISCLOSURE There is disclosed herein a specially designed rail cliphaving an opening through which a hold down device, such as a bolt, maypass, said clip having a two point bearing contact on a rail flange anda bearing contact upon the cross tie.

This invention relates to a railway rail fastener and relates moreparticularly to fasteners of the so-called resilient clip or clamp type,said fastener being particularly adapted for use in fastening railsections to concrete cross ties or sleepers.

According to the invention, there is provided a specially designed railclip having an opening through which a hold down device, such as a bolt,may pass, said clip having a two point bearing contact on a rail flange,and a bearing contact against an edge of the rail and bearing contactupon the cross tie.

An object of this invention is to provide an improved rail fastener ofthe type referred to which is particularly adapted for use with railsections laid on concrete ties or sleepers positively holding the same.

Another object of the invention is to provide a fastener of the typereferred to having improved holding power.

A further object of the invention is to provide a fastener of the typereferred to having an improved rail gage retaining member.

Another object of the invention is to provide an improved rail clip ofthe type referred to with greater fatigue life than present clips.

Yet another object of the invention is to provide an improved railfastener of the type referred to which can be fabricated in an improvedmanner.

A still further object of this invention is to provide an improved railfastener of the type referred to wherein the use of a tie plate is notrequired.

Another object of the invention is to provide an im proved rail'fastenerof the type referred to adapted to hold the rail in proper positionwithout creeping and adapted to further prevent lateral movementthereof.

Yet another object of the invention is to provide a fastener of the typereferred to adapted for use with various size rail gages.

A further object of the invention is to provide a fastener of the typereferred to which is of simple construction, economical, easilyinstalled and highly eflicient in use.

Other objects of the invention and a number of its advantages will bereadily understood from the following description of the invention andthe accompanying drawings, in which drawings: I

FIGURE 6 is a longitudinal vertical sectional view of 3,477,642 PatentedNov. 11, 1969 a rail section, concrete tie, rail pad, a pair of clips ofthe form of FIGURE 2 being applied thereto;

FIGURE 7 is a view similar to that of FIGURE 4 showing a modification ofthe clip of FIGURE 1;

FIGURE 8 is an enlarged sectional view taken on the line 8-8 of FIGURE6;

FIGURE 9 is a fragmentary enlarged detail of a rail contacting portionin one operative position; and

FIGURE 10 is a view similar to FIGURE 9 illustrating the portion inanother operative position.

In the embodiment shown in FIGURES 1 to 6, inclusive, and FIGURE 8, theimproved fastener of the invention is preferably constructed of a Tsection or T- shaped extrusion 10 of aluminum, heat hardened steel, orother resilient metal material, and said T-section being apertured toprovide an opening 11, preferably circular or ovate in form, thecircular opening being shown, said opening is medially positionedadjacent the areas contiguous one side of the stem or depending leg 12extending substantially at right angles to the planular body portion 13.The T section 10 is then preferably heated and bent to provide a flangeedge 14 arcuately bent or formed, as shown at a and b to providedownwardly extending biting edges 15 or spaced bearing points atopposite ends thereof wherefor a two point bearing contact on the railflange 16 is ensured by the free resilient end of the section 10.

The stem 12 is further, as shown, preferably integrally formed with thebody portion 13 and extends as shown the width of the clip. It isadapted, as best shown in FIGURE 6, to abut a substantial portion of theedge of the rail adjacent said flange surfaces upon which the clip hasbearing contact, as recited hereinbefore, thus backing up a substantialportion of the rail edge, and is of such limited depth that it is spacedabove the lower edge of said rail. The stem in use is force loadedsimilar to a leaf spring. The clearance obtained therefor between thebottom of the stem :and the sleeper 20 ensures the effect of the springloading.

During the forming of the flange edge 14, the opposite end of the clipis bent or deformed into a generally S-shaped yoke 17 and a relativelyflat upper terminal end 18. The said yoke 17 is adapted to seat in arounded cavity 19 affording a shoulder 19' in a concrete cross tie 20against which the end 18 abuts. Thus the clip is provided at one endwith a free resilient curved end having a two point contact by bearingportions 15 with the rail flange and provided with an opposite endbottoming in a recess afforded in the cross tie terminating a spaceddistance below the upper edge thereof, the same being dimensioned so asto be closely fitted therein making bearing contact therewith andprevented thereby from movement during creeping or lateral movement ofthe rail. The yoke 17 is disposed and bottoms on the crosstie, it willbe noted, below the level of the stem 12.

The fastener of this invention is heat treated to permit 7 the same notonly to be deformed as desired but preferably to render the same of suchresilient character as to permit a spring eflect whereby, upontightening the bolt 22 shown extending into tubular anchor nuts 23 insaid concrete cross-ties to secure the clip of the fastener to the railand cross-tie means 24, the clip bearing contact of portions 15 isincreased as best illustrated in FIG- URES 8, 9, and 10. Further uponvertical or wave movement of the rail the bearing contact by the edges15 is increased. The clip is preferably heat hardened to a desiredtemperature and quenched for a maximum fatigue life compatible with thespring quality desired.

It will be noted that the improved clip or fastener of this inventionhas improved holding qualities over prior art devices achieved by itssecure seating in the cross-tie and improvement in bearing contact withthe rail flange and rail edge and that the fastener resists transverseas well as longitudinal movement of the rail.

In the form of invention disclosed in FIGURE 6, a rail pad 25,preferably of polyethylene or rubber or other flexible material, isdisposed immediately beneath the rail undersurfaces interposed betweenthe rail and the sleeper 20 and is provided with arcuate notches (notshown) as will be understood by those skilled in the art to which theinvention pertains, partially encircling the fastener bolts 22. Thenotches, it is understood, vary in shape and size dependent upon theshape and size of the said bolts.

It will be noted that in the form of FIGURE 7 the opening 26 is, incontrast to the opening 11 of FIG- URES l to 6, inclusive, expanded toinclude a removal of portions of the T section adjacent the bolt toafford bearing contact with the bolt if desired to add support to thesame.

The clips of this invention may be used for rails of various size andgage, bolt spacing, dimensioning, etc. and may be varied to accommodatethe same.

It should be understood that although the clip is shown in directcontact and seating with the cross-tie that indirect contact therewithby means of different cross-members associated with the tie, such as atie plate, may be used.

While the invention has been described in connection with preferredembodiments, it will be understood that departures may be madetherefrom, without, however, departing from the spirit of the invention.
